Abstract
The invention discloses a seedling culturing matrix for producing organic selenium-rich watermelons. The seedling culturing matrix is characterized in that selenium-containing benne cakes serve as a selenium source and are used for producing seedling culturing matrix, the seedling culturing matrix consists of selenium-containing benne cakes 30-50 parts, rice husks 20-40 parts, fermented chicken manure 10-30 parts and river sand 10-20 parts. The seedling culturing matrix for producing the organic selenium-rich watermelons is simple and convenient to operate, reduces the labor intensity and labor cost in watermelon production, always provides enough selenium for the watermelons since watermelon seeds germinate and grow, accordingly enables the watermelons to absorb the selenium from soil in a whole growth period and convert the selenium into organic selenium through photosynthesis, and enables organic selenium proportion to be high and stable.
Description
Technical field
The invention belongs to the cultivating watermelon technical field, particularly a kind of seedling medium of producing the organic Se-rich watermelon.
Background technology
Selenium is the necessary trace element of human body, it is a kind of multi-functional life nutritional element, have anti-oxidant, regulate organism metabolism, improve immunity of organisms and premunition, improve and breed function, the opposing tumour, prevent and treat endemic (such as Keshan disease, Kaschin-Beck disease), delay senility the several functions such as the poisonous element of antagonism.Research in recent years shows that being related of the structure of selenium and cardiovascular system, function and disease thereof is close.Selenium enzyme-glutathione peroxidase has the reduction peroxide, anti peroxidation of lipid, the effect of Cell protection film.Heart is very sensitive to lacking selenium, and selenium deficiency can cause MDA to be piled up, and the LDL oxidation damage impels the angiocardiopathy genesis.The genesis that lacks the angiocardiopathies such as selenium and Keshan disease, atherosclerotic, coronary heart disease all has obvious correlation.
The people of nearly more than 40 countries and regions, the whole world is in poor selenium, low selenium band.China has more than 70% area, about 700,000,000 people be in poor selenium and low selenium district.Therefore, mending selenium is the requisite measure of these regional population healths.It is reported, present whole nation adult's selenium mean intake is 26.6 microgram/days only, almost only reach the necessary amounts lower limit 1/2 and better level 1/10, therefore most people need to increase as early as possible the intake of selenium, and should mend throughout one's life selenium, and the food by rich selenium to mend selenium be the approach of safer " multi-pronged ".Regulation in " dietary guidelines of nutrient supply and China in the every day meals " that Chinese Soclety of Nutrition is recommended, the day of selenium essential intake adult with teenager be 50 micrograms, children be 20 (1-3 year) to 40(4-6 year) microgram, the baby is the 15-20 microgram.Now, rational exploitation and utilization selenium resource, produce Selenium-enriched health food and natural selenium-rich food, become gradually a new focus of China's health food industry.
At present, " selenium yeast " of U.S.'s exploitation, kind (Centrum) the selemium nutrition additive and domestic of depositing
" rich selenium health ", " health must selenium " although etc. product belong to biological technology products, do not meet the food consumption present situation that large tracts of land lacks the selenium crowd, more can not become and lack effectively replenishing of the human selemium nutrition in selenium area.The academician such as Lu Liangshu, Li Zhensheng are pointed out; improving food chain selenium level is the fundamental solution of regulating and control selemium nutrition and the relevant selenium deficiency disease of prevention from the source; and appeal to strengthen the Se-rich farm products exploitation, and by common crop production selenium is organised, set up the human selemium nutrition pattern of daily food intake; strengthen rich selenium food production; have important business ﹠ economy and be worth, and build up people's health especially, (Lu Liang pardons the academician to the needs of protection people ' s health; the pollution-free food communication, on June 20th, 1999).
Watermelon has another name called water melon, cold melon, summer melon, is the fruit of cucurbitaceous plant watermelon, because being introduces from the Western Regions in the Han dynasty, so claim " watermelon ".Watermelon contains a large amount of glucose, malic acid, fructose, Argine Monohydrochloride, tomatin and the abundant materials such as vitamin C except not fatty and cholesterol, be good fruit in a kind of midsummer being rich in nutrition, pure, edible safety.At present, all adopt the method for foliage-spray inorganic selenium for producing rich selenium watermelon, its shortcoming is very obvious, and at first foliage-spray requires the fertile content of selenium higher, and the selenium fertilizer of high concentration has increased uses fertile cost; Secondly, because foliage-spray, selenium fertilizer is easy to unrestrained to the field, so just field runoff water and soil is caused very large waste; Again, often cause the inorganic selenium residual quantity large, and inorganic selenium has obvious toxic action to body, safety is lower, can not be used for the production of organic Se-rich agricultural product.
Summary of the invention
The objective of the invention is to provide a kind of seedling medium of producing the organic Se-rich watermelon.
For achieving the above object, technical scheme of the present invention is:
A kind of seedling medium of producing the organic Se-rich watermelon, made after mixing by following material and materials weight part ratio:
Contain selenium oil cake of flax seed 30-50
Rice husk 20-40
Fermentation poultry dung 10-30
River sand 10-20.
Have in the raw materials of the rich selenium seedling medium described in the technique scheme full Se content greater than 0.0015% contain the selenium oil cake of flax seed.
It is described that to contain the selenium oil cake of flax seed can be through farmers''s stack retting or use behind industrial composting.
Beneficial effect of the present invention is:
(1) adopt rich selenium seedling medium to produce the organic Se-rich watermelon, change in the past foliar application and produce the drawback of rich selenium watermelon, and it is fertile no longer to use the inorganic seleniums such as selenite, selenate, greatly reduces the environmental pollution that selenium fertilizer may cause, turn waste into wealth simultaneously, reduced production cost.
(2) rich selenium seedling medium provided by the invention is identical with conventional seedbed system matrix composition and application process, does not need specially treated, has saved the labour.And from Germination of Watermelon Seed is grown seedlings, just always for watermelon provides sufficient selenium source, thereby making watermelon can from soil, absorb and be converted into Organic Selenium by photosynthesis in whole vegetative period, the ratio of Organic Selenium is higher, and stablizes.
Embodiment
Below by specific embodiment technical scheme of the present invention is further described:
Field trial place: glad and village, Pudong New Area, Shanghai Lao Gang town, middle fertility.
For trying variety of watermelon: 8424.
The rich selenium seedling medium of present embodiment is comprised of the raw material of following parts by weight:
Batch production is become thoroughly decomposed and is contained 40 parts of selenium oil cake of flax seed, 30 parts on rice husk, 20 parts of fermentation poultry dungs, 10 parts of river sands, makes according to conventional seedbed system matrix preparation method.
Thickness of sowing is every square metre of 100 strains of growing seedlings, 0.5 centimetre of lid seedling medium thickness.
The watermelon maturation is measured the total selenium content in the watermelon juice afterwards, measures simultaneously the content of Organic Selenium and inorganic selenium.
After testing after the watermelon maturation, its fruit aquatic foods selenium content of squeezing the juice reaches 0.38 – 0.43mg/kg, and average out to 0.41mg/kg reaches rich selenium watermelon standard.Simultaneously, organic selenium content 84.2-88.5%.This shows and use total selenium and the organic selenium content that seedling medium of the present invention can the Effective Raise Watermelon Fruit.
